Argon Plasma Coagulation (APC)

This procedure allows the Gastroenterologist to seal irregular or bleeding tissue. It is performed during a panendoscopy or colonoscopy while the patient is sedated. This procedure involves using argon gas and electrical current to seal irregular or bleeding tissue without any direct contact.

APC is used in the treatment of conditions such as:

Barrett’s Oesophagus

Oesophageal Cancer

Rectal Bleeding (post radiation proctitis)

Colonic Polyps

Watermelon Stomach

Sedation

The surgical procedures provided at the Centre for Digestive Diseases do not require a general anaesthetic as intravenous sedation is given for these procedures. The Sedationist will insert a small needle into a vein in the back of your hand or in your arm through which the sedative will be injected. The injection may cause a local reaction. Bruising under the skin may occur, but should not cause permanent damage and is usually not painful. If you are having a gastroscopy procedure, your throat may be sprayed with an anaesthetic agent and may feel numb for a short time.

Complications

The procedures described above are considered to be safe. However, temporary discomfort or pain may occur following introduction of air into the stomach or bowel. Major complications are rare but can occur. These complications include perforation (puncture) of the oesophagus, stomach, duodenum, small bowel or colon. Haemorrhage (bleeding) following removal of polyps, infection, cardiac or respiratory arrest related to sedation / anaesthesia. If you wish to discuss the potential risks or any issues regarding your procedure(s) in more detail, please ask to speak with the Gastroenterologist.
